« [...] the issuer publishes the total capital, the total number of securities conferring the right to vote and voting rights, as well as, by category, the number of securities conferring the right to vote and voting rights vote, at the latest at the end of each calendar month in which an increase or a decrease in these numbers occurred.

| Nature of information | Remarks | |
| Amount of capital (EUR) | 42.502.318,54 | |
| Securities with voting rights =(A) | 30.282.218 | This is the basis for calculating the 30% threshold provided in article 5 of the takeover law of April 1, 2007 (Belgian Gazette 26.IV.2007). |
| Shares with voting rights | 30.282.218 | |
| Shares with loyalty voting right (section 28 of the articles of association) =(B) | 10.232.401 | |
| Existing voting rights =[A-B+(B*2)] | 40.514.619 | This is the denominator under which must be calculated the quota of voting rights that can give rise to notification in accordance with article 6 of the Law. |

Contact person for threshold crossing notifications: .
Shares endowed with the right to vote in loyalty: registered shares recorded in the share register for at least two consecutive years in the name of their holder (section 28 of the articles of association, in accordance with section 7:53 of the Companies and Associations Code).
Following the introduction of the loyalty voting right by decision of the general meeting of March 10, 2020, the calculation method used by IBA to determine the number of shares with the loyalty voting right at any time is the LIFO method (last in, first out), namely: for the same registered shareholder, the shares which the latter most recently acquired are the first shares which will be deducted from his “basket” of registered shares if he transfer shares thereafter.
Statutory ceiling (section 7, paragraph 1, of the articles of association: “No shareholder may, with companies and persons related to him, participate in the voting at general meetings for a number of votes exceeding 35% of the votes attached to all of the shares with voting rights issued by the company”): currently 35% of 40.514.619, i.e. 14.180.116,65 votes.
